[0002] When the longitudinal butt joint of the steel box girder bridge bottom plate is welded, the height is high, the danger coefficient is big, and the post-grinding paint repair work operation is difficult. The traditional method is to lay the operation platform along the bridge bottom plate for construction, which is complex, high in cost, has great influence on ground construction, and occupies the road for a long time. There are serious safety hazards in construction projects, and more manpower and resources are often invested to ensure safety, which also causes resource waste and cost increase. Moreover, the traditional construction method is slow and has low work efficiency. At present, most of the workers in high-altitude construction are migrant workers, who have relatively low safety awareness. If supervision is not in place, they will not construct according to the standard requirements, thereby greatly increasing the probability of safety accidents. Some safety accidents cannot be recovered, causing serious loss of personnel and property. Therefore, it is necessary to provide a device to solve the problems of narrow construction space on the top of the traditional bridge, the inability of construction personnel to move at will for construction, and the need to frequently change the fixing point of the safety rope.

[0003] The patent with publication number CN212000637U discloses a movable operation platform for a mobile support, which moves the operation plate by the connecting plate walking on the track in reverse, and the workers can perform corresponding operations on the operation plate.

The operation plate and the connecting plate can be detachably arranged, so that the operation platform can follow the mobile support through the hole, reducing the complex disassembly and assembly process and further increasing the work efficiency. Moreover, the arrangement mode of the operation platform is not affected by the terrain and bridge position, and has a wide range of use. However, there is no channel for the workers to move up and down between the operation plate and the bridge deck. When the workers need to move up and down, they still need to rely on the safety rope.

[0004] The patent with publication number CN213538689U discloses a sliding construction platform for assisting in welding the weld of a steel beam, which sets a pulley to realize the longitudinal movement of the platform on the cantilever arm, thereby providing a suitable special construction platform for the welding of the super-long cantilever arm of the steel bridge, and effectively solving the problem of high difficulty in welding the super-long cantilever arm.

[0026] In the implementation process, the hanging column 2 is arranged in the structure of the reinforcing crosspieces 22 and the vertical rods 21, which not only increases the stability of the hanging column 2 itself, but also increases the connecting points between the ladder 4 and the hanging column 2 through the reinforcing crosspieces 22, thereby increasing the connecting stability of the ladder 4 and improving the safety. Figure 3 As shown, two connecting ribs 5 are welded at each reinforcing crosspiece 22. Since the distance between the adjacent reinforcing crosspieces 22 is large, it is not suitable for the worker's step distance, so a special ladder 4 is additionally arranged for the worker to move up and down.

[0027] The erection process of the operation platform is as follows:

[0028] The moving assembly 3 is installed at the cantilever 6 position of the bridge surface in advance;

[0029] The construction platform 1, the hanging column 2 and the ladder 4 are integrated on the ground, then hoisted to the cantilever 6 position of the bridge surface, and connected with the pre-installed moving assembly 3 through high-strength bolts.

[0030] During construction, the worker can control the moving assembly 3 to realize the longitudinal translation of the operation platform along the bridge surface, and perform the longitudinal butt joint welding of the bridge bottom plate 12 and the later polishing and painting work.

[0031] In order to improve the safety of the worker when getting on and off the ladder 4, as shown in the embodiment, Figure 1 The construction platform 1 protrudes from the end of the cantilever 6 along the lateral direction of the bridge surface to form a ladder space 7, and the ladder 4 is arranged on the side of the ladder space 7 of the construction platform 1.

[0032] In the implementation process, as shown in the embodiment, Figure 1 The left side of the construction platform 1 is flush with the end of the bridge surface, and the upper and lower ends of the left hanging column 2 are respectively adjacent to the end of the bridge surface and the end of the construction platform 1. The right side of the construction platform 1 extends outward from the end of the bridge surface, and the construction platform 1 platform is left on the side of the right hanging column 2 away from the bridge surface for the worker to stand when getting on and off the ladder 4.
